– Used to prioritize voice traffic while marking other traffic (such as video) for better QoS or for best effort (such as Internet traffic).

• Hierarchical Input Policer

– Supports up to three levels of hierarchy in the policer.

– Enables limiting all traffic to a customer and limiting the voice, video, or data traffic as a subset of the total allowed bandwidth. This is used when oversubscribing all traffic while still guaranteeing minimum bandwidth for critical traffic.
